This is a remix of the airlock posted by bettapro. I needed a longer stem for my rubber cork, the hat was a little tight so added two more slots as well as vent holes and I modified the float a little with hopes the top of the float will print a little better for me.

Airlock_Body_V2a uploaded. The connection between the body and the stem was missing a hole and that has been corrected. If you downloaded the previous version of the body you will have to drill it out at the connection between the stem and body or download this new one and print it. I made the base of the body thicker to prevent leaks.
